The AD7398/AD7399 family of quad, 12-bit/10-bit, voltage output digital-to-analog converters is designed to operate from a single 3 V to 5 V or a dual ±5 V supply. Built with Analog’s robust CBCMOS process, this monolithic DAC offers the user low cost, and ease-of-use in single or dual-supply systems.
The applied external reference VREF determines the full-scale output voltage. Valid VREF values include VSS < VREF < VDD that result in a wide selection of full-scale outputs. For multiplying applications ac inputs can be as large as ±5 VP.
